🍴 Recipe Tips
Make sure to use microwave-safe cling wrap and bowls to cook yellow squash in microwave. This is probably the most important thing to mention as not everything is microwave safe!
Microwaves also vary in strength so the time needed to cook your squash may vary. The goal is to have it look slightly translucent (or as translucent as you want).
I prefer my summer squash to have a bit of a firm fresh bite to it around the outside but still soft in the center. You can always add another 30 seconds- 1 minute and check on it if it's not done to your liking.
The water is added by sight, not by actual measure. You want just enough to cover the bottom of the bowl, by about ½-1 inch of depth.
💭 FAQs
Absolutely! Use a combination of yellow squash and zucchini or one or the other, depending on what you have on hand.
Yellow squash is a good source of fiber and vitamins like A, B6, and C. They also have a decent amount of potassium. They're a nutritional veggie that's often very affordable when in season in the Fall.
You can cut and prep your yellow squash and onion bowl and cover it in the fridge up to a day in advance. You can also slice the yellow squash and simply keep it in a Ziploc for about 1-2 days before cooking, but keep in mind it may dry out if not properly sealed.

I haven’t made this yet but I’m looking at the nutrition since I’m on keto. The serving size says 1 scoop— how much is that 1/4 cup?? Looks good. Thanks

It's about a heaping 1/4 cup of cooked squash.
